public enum ConsolFunextends Enum<ConsolFun>
Enumeration of available consolidation functions. Note that data aggregation inevitably leads to loss of precision and information. The trick is to pick the aggregate function such that the interesting properties of your data are kept across the aggregation process.

  • Enum Constant Details

    • AVERAGE

      public static final ConsolFun AVERAGE
      The average of the data points is stored.

    • MIN

      public static final ConsolFun MIN
      The smallest of the data points is stored.

    • MAX

      public static final ConsolFun MAX
      The largest of the data points is stored.

    • LAST

      public static final ConsolFun LAST
      The last data point is used.

    • FIRST

      public static final ConsolFun FIRST
      The fist data point is used.

    • TOTAL

      public static final ConsolFun TOTAL
      The total of the data points is stored.

  • Constructor Details

    • ConsolFun

      private ConsolFun()

  • Method Details

    • values

      public static ConsolFun[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static ConsolFun valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • getVariable

      public abstract Variable getVariable()
      Creates the variable that applies this consolidation function.
      Returns:
      the Variable implementation that applies this consolidation function
